The AtriCure Bipolar Coagulation System is intended to ablate and coagulate soft tissue during General, ENT, Thoracic, Gynecology, and Urology surgical procedures.
The AtriCure Bipolar Coagulation System consists of two components: AtriCure Bipolar Coagulator and AtriCure Bipolar Electrosurgical Generator.
The Bipolar Coagulator is substantially equivalent to the predicate Bipolar Forceps in that each consists of a handle connected to a pair of grasping jaws with electrodes on each jaw arm. All the devices utilize the same bipolar Electrosurgical technology, i.e., radio frequency (RF) energy, to coagulate the tissue by heating. The Bipolar Coagulator contains a negative and positive electrode on opposite jaw arms. The function of the Bipolar Coagulator and predicate devices is the same, current flows from a negatively charged pole through the tissue to a positively charged pole. The Bipolar Coagulator is provided as a sterile single patient use device and is provided in a variety of shapes and sizes. The Bipolar Coagulator is constructed with standard biocompatible materials used in medical devices involved in tissue contact.
The Bipolar Coagulator is designed to grasp tissue between the electrodes. When the energy is applied, the tissue touching the electrodes is coagulated. The field of coagulation extends up to 2 mm from the electrode. Area of coagulated tissue will be up to 4 mm in width or up to 60 mm in length. Fully coagulated tissue can be achieved for tissue thickness less than 10 mm.
The Electrosurgical Generator is set to deliver 750 mA of current. As tissue coagulation proceeds the impedance increases. The voltage is set to not exceed 75 Volts. When a voltage of 75 Volts is reached, the impedance increases and current flow decreases with voltage maintained at 75 Volts. Impedance of 400 ohms typically indicates fully coagulated tissue. The unit will display impedance, current, voltage, and power on the front of the generator. The unit will also monitor the temperature of the coagulated tissue and has a range up to 125 degrees Celsius. The surgeon may also use this temperature reading as a point of reference to determine the extent of tissue coagulation.
The provided submission is a 510(k) summary for the AtriCure Bipolar Coagulation System. It focuses on demonstrating substantial equivalence to predicate devices and adherence to relevant industrial/international standards. However, it does not contain a study that proves the device meets specific acceptance criteria in terms of performance metrics like sensitivity, specificity, accuracy, or efficacy in a clinical or simulated environment.
The document primarily describes the device, its intended use, and lists predicate devices, along with compliance with various safety and quality standards (e.g., ISO, IEC, UL). These standards relate to electrical safety, biocompatibility, sterilization, and packaging, but not to the clinical performance or diagnostic accuracy of the device.
Therefore, many of the requested sections regarding acceptance criteria and study details cannot be fulfilled from the provided text.
Here's an analysis based on the available information:
1. A table of acceptance criteria and the reported device performance

| AAMI ESI-1993 (Safe Current Limits for Electromedical Apparatus) | Meets standard |
| IEC/EN 60601-1 (General Requirements for Safety) | Meets standard |
| IEC/EN 60601-1+1 (Safety Requirements for Medical Device Systems) | Meets standard |
| IEC/EN 60601-2 (Electromagnetic Compatibility - Requirements and Tests) | Meets standard |
| IEC/EN 60601-2-2 (Safety of High Frequency Surgical Equipment) | Meets standard |

| ISO 11137 (Sterilization of Health Care Products, Sterilization of Gamma Irradiation) | Meets standard |
| Quality Management Standards | |
| EN 46001 (Application of EN ISO 9001 to the Manufacture of Medical Devices) | Meets standard |
| Functional Capabilities | |

Note on this table: The "reported device performance" columns for the standards indicate that the device "meets" them. This implies successful testing against these standards, but the specific test results or detailed acceptance criteria for those tests are not provided in this 510(k) summary. The functional capabilities describe the physical characteristics and operational parameters of the device, which are inherent design specifications rather than performance metrics from a formal study proving efficacy.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This information is not provided in the submission. The submission primarily relies on demonstrating substantial equivalence to predicate devices and compliance with recognized industrial/international standards. There is no mention of a clinical or ex-vivo test set with specific sample sizes or data provenance for proving performance.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This information is not applicable/provided. No clinical or diagnostic performance study using expert-established ground truth is described in the document.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This information is not applicable/provided. No clinical or diagnostic performance study requiring expert adjudication is described in the document.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
This information is not applicable/provided. This device is an electrosurgical system, not an AI-assisted diagnostic tool. Therefore, an MRMC study related to human readers improving with AI assistance would not be relevant to this submission.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This information is not applicable/provided. The AtriCure Bipolar Coagulation System is a medical device for ablating and coagulating tissue, not a standalone algorithm. Its performance is intrinsically linked to its use by a human surgeon. The document describes the technical specifications and safety compliance of the device itself.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
This information is not applicable/provided in the context of a performance study establishing efficacy or diagnostic accuracy. The "ground truth" implicitly referred to would be the successful adherence to engineering and safety standards during testing, and the physical parameters of tissue coagulation as observed in bench testing or internal validation, but no formal 'ground truth' for clinical efficacy is reported.
8. The sample size for the training set
This information is not applicable/provided. This device is not an AI/ML algorithm that requires a training set.
9. How the ground truth for the training set was established
This information is not applicable/provided. This device is not an AI/ML algorithm that requires a training set with established ground truth.
